Michael C. Hall has listed a property in Los Feliz at $4.5 million. Considering that the "Dexter" star and serial home buyer purchased the place a year ago at $3.825 million, he may not make much of a killing after improvements and commissions.

The updated 1920s Spanish Colonial and guesthouse feature arched windows, beam ceilings, wrought-iron work, French doors and wood floors. A foyer, living and dining rooms, a library, six bedrooms and six bathrooms are within the 5,618 square feet of living space.

------------FOR THE RECORD: Hot Property: A July 20 Business section column on celebrity real estate transactions said Julie Chen has been the host of "Big Brother" since 2010. She has been the host since the TV show began in 2000. ------------

The gated grounds contain an entry garden, a swimming pool and a detached three-car garage.

Hall, 43, starred as the murder-minded title character on "Dexter" from 2006 until last year. Before that he was on HBO's funeral-home drama "Six Feet Under" (2001-05). He was in this year's big-screen thriller "Cold in July."

Actors fall for Bing Crosby house

Megan Fox and Brian Austin Green, who are hoping to soon be home sellers, have already snatched up a new place in Toluca Lake for $3.35 million.

Features include exposed beams, vaulted ceilings, skylights, a library, a recreation room, four bedrooms and six bathrooms. The 563-square-foot pool house has its own kitchen.

Moving up along the beach

Les Moonves, chairman and chief executive of CBS Corp., and his wife, TV personality Julie Chen, have sold their La Costa Beach home in Malibu.

The sales price has yet to appear in the public record, but the most recent asking price was $11.995 million.

The transaction comes as no surprise. Moonves and Chen bought billionaire and Microsoft Corp. co-founder Paul Allen's place on Carbon Beach this spring for $28.8 million. That house has five bedrooms and seven bathrooms in 6,500 square feet of living space.

On the main level of the house the couple just sold, a great room combines the living room, a dining area and a kitchen with stainless-steel appliances and an island. The rooms open to an ocean-view patio. There are teak floors throughout.

Other rooms in the 3,014 square feet of space include a den/media room, a master bedroom with a fireplace, two guest bedrooms and four bathrooms. The entry courtyard contains a spa.

Moonves, 64, married Chen, 44, a decade ago. Chen has been a news anchor and appears on "The Talk." She has been the host of "Big Brother" since 2010.

They bought the property in 2008 for $10 million, public records show. The couple also own a house in Beverly Hills.

Buzz Aldrin has parted with his out-of-this-world condo along the Wilshire Corridor for $2,865,955.

Built in 1990, the three-bedroom, 3.5-bathroom condo features an open floor plan, floor-to-ceiling windows and custom built-ins. Outer space includes two balconies.

The corner unit has 3,143 square feet of living area and unobstructed views of the cityscape, the nearby Wilshire Country Club golf course and vast expanses of the cosmos.

Aldrin, 84, was the second man to walk on the moon in 1969.

He paid $1.34 million for the property in 1998, public records show.

Karen and Steven Heiferman of Hilton & Hyland/Christie's International Real Estate were the listing agents. Peter Maurice of Rodeo Realty represented the buyer.

A plot twist in Brentwood

Thomas Schulman, an Academy Award-winning screenwriter, has sold his Brentwood home to film producer Michael LaFetra for $10.5 million.

Designed by architect Steven Ehrlich and built in 1992, the Modernist house is set on 1.35 acres at the end of a bamboo-lined driveway. The 9,000-square-foot house is accessed by an entry bridge.

Inside are a two-story living room, two offices, a game room, a media room, a library, five bedrooms and seven bathrooms.

Schulman, also a director and producer, won his Oscar for writing "Dead Poets Society" (1989). Other writing credits include "Welcome to Mooseport" (2004) and "8 Heads in a Duffel Bag" (1997).

LaFetra is a house collector and renovator, often buying homes of note, restoring them and returning them to the market. He has listed the Frank Gehry-designed Schnabel House at slightly less than $15 million.

Timothy Enright of the Enright Co. was the listing agent for Schulman. Cory Weiss of Douglas Elliman represented LaFetra.
